Is blowgun fast enough to this?

Cannons powered by pneumatic pressure (compressed gas) using a valve or other release.

I am doing a copper valve piston air cannon and as pilot works a normal blowgun "DG-10" and tee`s ID is 32mm and barrels ID 20mm and OD 22mm and pilot volume is something 10cm3-15cm3+tube`s volume that goes to the blowgun (something 5cm3) and my question is that,does the blowgun exhaust fast enough to launch valve?

Yea, that's definitely going to get you at least a tazer.

No, low ID, a higher ID will create a higher pilot volume. The flow of the lower ID tubing will still beat the blowgun unless it's stupidly narrow, and the low volume will exhaust quicker.

I have to ask... are you a UK resident? It's just when you say 22mm copper, that immediately rings bells.

Anyway, that should work as long as your piston is a good fit. If it's too loose, you might loose some power.
Does that thing kinda look like a big cat to you?

Been thanked: 1 time

Why not get rid of the hose altogether and use an elbow like this.

Makes a nice ergonomic position for the trigger too.
Edit: Just realised my blowgun is a dg-10 also :D

When you fill your car with refined oil remember that it has been paid for with blood and guts, some from your own countrymen, most not.

It's actually pretty good. I've seen much worse from people who speak it as a native language.
